Abstract

Se proporciona un metodo para purificar un polipropileno reciclado. El método involucra obtener polipropileno reciclado, al ponerlo en contacto con un primer solvente fluido para producir un polipropileno reciclado extraido despues de disolver el polipropileno reciclado extraido en un solvente para producir una primera solucion que comprende polipropileno y contaminantes suspendidos. La primera solucion se sedimenta para producir una segunda solucion que comprende polipropileno y contaminantes restantes. La segunda solucion se purifica al poner en contacto la segunda solucion con medio solido para producir una tercera solucion que comprende polipropileno mas puro. Finalmente, el polipropileno mas puro se separa de la tercera solucion.
